Abstract
An electrically commutated, collectorless direct-current motor is disclosed whose stator has a self-supporting drum winding and a cylindrical plastic body which is located concentrically with the drum winding in a winding head. The cylindrical plastic body has recesses which contain eyehooks. The ends of the drum winding are connected with the eyehooks, which are welded to a circuit board. The invention makes it possible to automate the connection of the winding ends to the circuit board.
